Medial collateral ligament (MCL) injury is the most common knee ligament injury in professional football.
To investigate the rate and circumstances of MCL injuries and development over the past decade.
Prospective cohort study, in which 27 professional European teams were followed over 11 seasons (2001/2002 to 2011/2012). Team medical staffs recorded player exposure and time loss injuries. MCL injuries were classified into four severity categories. Injury rate was defined as the number of injuries per 1000 player-hours.
346 MCL injuries occurred during 1 057 201 h (rate 0.33/1000 h). The match injury rate was nine times higher than the training injury rate (1.31 vs 0.14/1000 h, rate ratio 9.3, 95% CI 7.5 to 11.6, p<0.001). There was a significant average annual decrease of approximately 7% (p=0.023). The average lay-off was 23 days, and there was no difference in median lay-off between index injuries and reinjuries (18 vs 13, p=0.20). Almost 70% of all MCL injuries were contact-related, and there was no difference in median lay-off between contact and non-contact injuries (16 vs 16, p=0.74).
This largest series of MCL injuries in professional football suggests that the time loss from football for MCL injury is 23 days. Also, the MCL injury rate decreased significantly during the 11-year study period.
内侧副韧带（MCL）损伤是职业足球中最常见的膝关节韧带损伤。
调查过去十年中 MCL 损伤的发生率和情况。
前瞻性队列研究，对 27 支欧洲职业球队进行了 11 个赛季（2001/2002 至 2011/2012）的跟踪研究。球队医务人员记录了球员的暴露和伤病时间。MCL 损伤分为四个严重程度类别。损伤发生率定义为每 1000 名球员小时的损伤数。
1057201 小时内发生 346 例 MCL 损伤（发生率为 0.33/1000 小时）。比赛中的损伤发生率是训练中的 9 倍（1.31 比 0.14/1000 小时，发生率比 9.3，95%CI 7.5 至 11.6，p<0.001）。每年平均下降约 7%（p=0.023）。平均休战时间为 23 天，且首次损伤和再次损伤的中位数休战时间无差异（18 天比 13 天，p=0.20）。近 70%的 MCL 损伤与接触有关，接触性损伤和非接触性损伤的中位数休战时间无差异（16 天比 16 天，p=0.74）。
这是职业足球中最大的 MCL 损伤系列研究，表明足球运动员因 MCL 损伤而损失的时间为 23 天。此外，在 11 年的研究期间，MCL 损伤发生率显著下降。
